PAINT AND VARNISH REMOVER.

.and useful Improvements in Paint and-Varnish Removers, of which the following is a The object of my invention is to produce an improved aint and varnish remover which will er orm its work in faster time than is possible with the present agencies of the kind, and which shall perform its work is such a manneras to eliminate the need for going over with benzin the surface of the material from which the paint or varmover of a fluid consistency, sufiiciently paint and varnish remover. Tallow applied as described below will thicken the fluid sufficiently and allow the coatings thereof to be wiped off without removing the filling or stain and without necessitating a further going over of the surface with benzin.

My paint and varnish remover consists of acetone, by volume twenty-six per cent, denatured alcohol twenty-four and one-half per cent; refined benzin seventeen per cent;

It also consists in a paint and varnish reether three per cent.; tallow twenty per cent., powdered ammonium carbonate one and one-half per cent, and turpentine eight alcohol and turpentine and ammonium car-.

bonate are heated together, and the warm tallow is added and shaken .until thoroughly incorporated. The refined benzin, ether and acetone in a cold state are then mixed therewith, shaken for about ten minutes and the resulting mixtures strained.

In paint removers at present in use the principal active ingredient is wood alcohol. The fumes of Wood alcohol are extremely injurious and for this reason I have adopted the combination of ether, ammonium carbonate, acetone and denatured alcohol, which acts with the commercial efiiciencv of ..wood alcohol and without its injurious effects. The volatility of the substances last above referred to interfere-with their activity for the purpose. in view. But ;both the turpentine and the tallow'tend to retard evaporation and therefore produce the desired result. I

Having described my invention, what I claim as new and desire to secure'byLetters Patent of the United States is:

In a paint and Varnish remover the combination with acetone, denatured alcohol, refined benzin, ether, ammonium carbonate, and turpentine, of twenty per cent.. of tallow mixed and combined substantially as described, whereby the after treatment of the surfaces by benzin would be rendered unnecessary.

In testimony whereof, .I have hereunto subscribed my name, in the presence of two subscribing witnesses, in the city and county of San Francisco and Stateof California this 27th day of August, in the year 1910. JAMES NICLES. In the presence of- FRANK P. MEDINA,
